Definitions

  • the invention relates to an adhesive tape for the flying role change of wound on rolls flat web material and the use of such adhesive tape.
  • the flying reel change is a common method to replace an old, almost unwound roll with a new role, without having to stop the fast-running machines for it.
  • pressure-sensitive adhesive tapes are often used to connect the end of the old web to the beginning of the new web.
  • flying reel change also called “dynamic reel change”
  • dynamic reel change takes place in the paper, foil and nonwoven processing industry according to two different methods.
  • double-sided adhesive self-adhesive tapes are glued by hand at the web start of the web of the new roll in an advantageous arrangement (usually W- or V-shaped), and the projecting on the adhesive tape web material is separated.
  • the beginning of the web of the new roll is fixed to the underlying roll of the new roll with so-called hold-down labels to prevent the web from being unwound as the new roll accelerates to the surface speed of the old roll.
  • a disadvantage of this method is that the preparation of the rollers is very time consuming and the bonding requires the use of professionals.
  • the method does not always lead to the desired results, since the bonds thus obtained are relatively thick because of the layering of web material, retaining labels and adhesive strips.
  • a double-sided self-adhesive tape is stuck in a straight line under or over the uppermost layer of the roll-shaped material.
  • the US 5,323,981 discloses a two-sided adhesive tape having on the front side a combattackige adhesive for the flying role change.
  • two adhesive mass portions are positioned, which advantageously have an adhesive mass-free zone between the portions.
  • the rear adhesive mass portion which is permanently adhesive, glued to the uppermost layer of the new role and the front adhesive mass portion which is repositioned, glued beyond the uppermost layer reaching out to the second layer.
  • the repositionable adhesive mass portion in this variant fulfills the object of a roller shutter.
  • flying reel change occurs on the front of the tape to the contact of the expiring web with the new role.
  • the repositionable adhesive portion detaches from the second layer material and the new roll is retracted into the machine held by the permanent adhesive at the end of the adhesive tape.
  • the WO 95/29115 A discloses a similar adhesive tape.
  • This two-sided adhesive tape has two adhesives on the upper side (front side) and an adhesive on the lower side (rear side).
  • the tape is fixed under the top layer of the new roll.
  • the one adhesive of the top holds the topmost layer.
  • the second adhesive on the top is responsible for contact with the running web.
  • On the underside is a repositionable adhesive which, in the case of the "splice", ie when the new roll begins to work, releases its uppermost layer.
  • the DE 198 41 609 A describes a two-sided adhesive adhesive element. Its carrier is not made of a single-layer paper, but of a paper / paper composite, which is connected with curing adhesive dots. This adhesive element is also glued under the top layer of the new role. In the case of the splice, the adhesive dots tear paper fibers from one of the composite papers, and thus the topmost layer is released.
  • the detection of the position of the adhesive tape for the splice in the roll changer can be done optically or inductively.
  • the WO 03/018451 A describes an adhesive tape which is colored on the contact side to the running web so, preferably black, that an optical detection and thus a timely release of the splice is ensured.
  • the page dyed for detection shows in the case of the adhesive tape (relative to the new roll) radially outwards, so that sensors on the roll changer can detect the adhesive tape.
  • the coloring can be done by printing the support material on the side, to which the adhesive is later layered for contact with the running web.
  • the EP 1 041 025 A describes an adhesive tape having a support with aluminum foil. About this inductive detection is triggered.
  • the detection of the splice residues in the finished printed product can be effected by the use of labels which project beyond the roll edge.
  • this method has the possibility of errors that the labels are lost in the printing process, so that the splice residues can not be sorted out safely.
  • some additional copies must always be sorted out to make sure that all copies are sorted out with a splicer test.
  • An inductive detection has the advantage that the splice residues can be safely sorted out, and it can also be sorted out every single copy that contains a splice test. It must therefore be sorted out much fewer copies, which is reflected in a cost reduction.
  • the adhesive tape must be accurately detected at the beginning of the roll change process so that the position of the adhesive tape can be reliably determined and thus the splice can also be carried out safely.
  • the splice residues must be reliably detected in the finished printed product in order to ensure the ejection of the printed products which contain a splicer test.
  • none of the detectable additives may be visible after the splicing process while passing through the printing press. Namely, modern printing machines have a sensor to quickly detect ripper and to be able to stop the printing process quickly to keep the losses low. Now, if one of the detectable additives is obviously recognizable, the sensor no longer recognizes the normal paper, but e.g. the aluminum foil or the black coloring, and can detect this as a paper ripper, which then leads to malfunctions in the running process.
  • the adhesive tape according to the invention is optically detectable on its front side, as is necessary for the preparation and the course of the flying reel change, i. for the splice, is required.
  • a finishing machine e.g. a printing machine for paper
  • the splice residues can be detected inductively.
  • the inductively detectable device preferably an aluminum foil
  • the above-described latest printing presses also operate without malfunction.
  • Visually inconspicuous (optically neutral) means, in particular, that the inductively detectable device is not recognized by a sensor which is intended to detect paper scrapers or is not distinguished from a normal paper surface, for which purpose some embodiments are specified in the subclaims and the exemplary embodiments described below.
  • a two-sided smooth Kraft paper of, for example, 55 microns thick and a basis weight of 65 g / m 2 is provided as a carrier, which is printed on one side (referred to as the front) with a black ink.
  • the kraft paper may be painted, resulting in a better anchoring of the ink.
  • Important to the paper are the physical properties, especially the breaking strength. This must be higher than the web tension in the press or other processing machines used. For machines with lower web tension, the paper can also be made thinner. This would have advantages for the manufacturing process, as thinner materials are less disruptive to the machine pass.
  • an aluminum foil is laminated in a further process as an inductively detectable device.
  • the aluminum foil is usually present in a thickness of 6 microns to 12 microns. Depending on the sensor type, it can also be thinner or thicker. Again, thinner composites are less disruptive to machine flow than thick composites.
  • the lamination can be done for example via a two-component adhesive or by means of polyethylene. Methods to generate such a composite are well known.
  • the film can have the same width as the backing paper, but can also be used narrower.
  • This aluminum foil is printed with a white printing ink. This ensures that a sensor for zippers in a modern printing press is not disturbed by the passage of the aluminum foil and therefore also detects or reports no ripper.
  • This multiple composite is coated on the black printed side (ie the front) with an adhesive (self-adhesive).
  • the adhesive must be chemicaltackig, that is high Anjankleb manufacturer and have high bond strengths.
  • the adhesive is covered with a siliconized material, preferably a silicone paper. If the adhesive tape is processed manually, this detachable cover can have a slit, ie be segmented, so that the resulting sections can be pulled off independently of one another. On the other hand, if the adhesive tape is to be used in an automatic process, a non-slotted masking material may be more advantageous.
  • the cover material is preferably paper, since it is then hand tearable. In an automatic application, the cover material may also consist of a film, since in this case the adhesive tape with cover is cut by machine.
  • the determination of the initial tack was carried out as follows: The so-called rolling ball tack was measured as a measure of the tack with a very short contact time.
  • a standard polyester support having a thickness of 23 ⁇ m of the respective self-adhesive composition was coated on one side (self-adhesive application after evaporating off the solvent: 50 g / m 2 ).
  • An approximately 10 cm long strip of the adhesive tape was attached with the adhesive side up horizontally on the test plane.
  • a sample ball of steel (diameter: 11 mm, mass: 5.6 g) was cleaned with acetone and kept for 2 h in a room atmosphere (temperature: 23 ° C +/- 1 ° C; relative humidity: 50% +/- 1% ) conditioned.
  • the steel ball was accelerated by descending from a 65 mm high ramp (inclination angle: 21 °) in the gravitational field of the earth. From the ramp, the steel ball became directly on the adhesive Surface of the sample steered. The distance traveled on the adhesive until the ball stopped was measured.
  • the thus determined taxiway length serves as an inverse measure of the initial tack of the self-adhesive (ie, the shorter the taxiway, the higher the tack, and vice versa).
  • the respective measured value resulted (as length specification in mm) from the average value of five individual measurements.
  • the determination of the bond strength was carried out as follows: The paper side of a single-sided adhesive SC paper (SC: "super calendered") bonded to a base was used as a defined adhesion or test substrate (adhesive panel). As the sample to be investigated, a standard polyester support having a thickness of 23 ⁇ m was coated on one side with the respective self-adhesive composition (self-adhesive composition after drying the solvent: 50 g / m 2 ). A 20 mm wide strip of the coated standard polyester carrier was pressed onto the SC paper under load (2 kg). Immediately thereafter, the adhesive tape was peeled off from the substrate at a speed of 300 mm / min at an angle of 180 ° and the force required for this at room temperature was measured. The measured value (in N / cm) was the average of three individual measurements.
  • the adhesive of the contact side front side
  • the side after sticking to a new role radially outwardly facing side increased shear values.
  • the measurement of the shear strength is carried out as follows:
  • any Crosslinking of the adhesive is a strip of 13 mm width and at least 20 mm in length cut out and on a defined paper (eg gravure paper, eg Neopress T 54, 54 g / m 2 , or base paper, eg Mediaprint, 135 g / m 2 ) glued.
  • the bond area is 13 mm x 20 mm.
  • test sample thus produced is loaded with a weight of 1 kg parallel to the bond plane and the time that the adhesive strip remains on the paper is measured.
  • test temperatures eg 40 ° C. and 70 ° C.
  • Such a product with increased shear values is particularly used in printing presses in which, in addition to a "cold-set” printing unit, a "heat-set” printing unit is also present. This will be increasingly the case in the future as it can increase the effectiveness of printing presses.
  • a fissile system is applied, which can fix the top layer of a new roll with flat material on the underlying layer, as explained above.
  • This fissile system can have a wide variety of embodiments.
  • the DE 199 02 179 A described may be a paper coated on both sides with adhesive, which splits in loads in the Z direction in itself and thus covers the adhesives necessary for bonding.
  • Z-direction loads are force components perpendicular to the plane of the beam as they occur when the flat web material is unrolled from the new roll and the top layer detaches from the underlying layer.
  • Both on the back of the carrier facing adhesive and the adhesive on the other side of the paper may be self-adhesive. However, it is also possible to use curing adhesives.
  • Curing adhesives to the support have the advantage that they can be applied in smaller layer thicknesses and thus reduce the thickness of the overall system. Curing adhesives on the other side, ie the side to be bonded to the web material, offer the advantage that particularly difficult bonding substrates are securely bonded. Such adhesives are e.g. activated by water or other solvents or heat. Although more time is required in the use of such adhesives, because the adhesive must be activated and the tape to be applied and then cure the adhesive. But this can be realized in today's production cycles, as often works with central Splicevorkung. The roles are usually prepared 6 hours to 8 hours in advance.
  • a single-ply paper can also be a paper / paper composite, as in EP 1 076 026 A described, a paper / foil composite or a film / foil composite are used.
  • the splitting force of all systems described should be between 15 cN / cm and 70 cN / cm.
  • FIG. 1 shows a schematic cross section through the designated adhesive tape 1, which is not shown to scale and in particular greatly exaggerated.
  • the width direction of the adhesive tape 1 extends from left to right and thus when used in the longitudinal direction of the flat web material to be joined with the adhesive tape 1.
  • a two-sided smooth kraft paper 2 as a carrier of eg 55 microns thickness and a basis weight of 65 g / m 2 with a front 4 and a back 5 is with a layer 6 with black Printing ink printed as an optically detectable device. As described above, it may be a one-sided or double-sided coated paper. The printing takes place on the front side 4, that is to say on the side which points radially outward, when the adhesive tape 1 is glued onto a new roll of flat web material.
  • an aluminum foil 8 is laminated as an inductively detectable device. This is printed on the radially inwardly facing side with color, whereby a cover layer 9 is formed, so that the aluminum of the aluminum foil 8 is not visible.
  • This color is preferably white, i. papery.
  • a high-tack self-adhesive 10 ("pressure-sensitive adhesive", contact adhesive) is applied over the layer 6. This may be transparent, so that the black printing of the layer 6 shines through, or may itself be darkened in order to improve the detectability.
  • the self-adhesive composition 10 is covered with a removable cover 12, which is divided by a slot 13 into two segments 14, 15.
  • a fissile system is positioned, which in the embodiment according to FIG. 1 consists of a splittable paper 16 and two adhesives 17 and 18 configured as self-adhesive compositions.
  • the positioning thereof is advantageously carried out by 1 mm to 15 mm offset from the edge 19 of the adhesive tape 1, see FIG. 1 ,
  • FIG. 2 shows a second embodiment of the adhesive tape designated here by 20, in which the layer sequence is different than in the adhesive tape first
  • a double-sided smooth kraft paper 22 as a carrier of eg 55 microns thickness and a basis weight of 65 g / m 2 and with a Front 24 and a back 25 is laminated on its front side 24 with an aluminum foil 28.
  • the thickness of the aluminum foil 28 is again between 6 microns and 12 microns.
  • the inductively detectable device in the form of aluminum foil 28 is thus arranged here on the front side 24 in contrast to the first embodiment.
  • This composite is printed on the aluminum foil 28 to produce an optically detectable layer 26 black.
  • a high-tack self-adhesive composition 30 contact adhesive
  • the cover 32 is not segmented, so has no slot, which is more advantageous in an automatic application of the adhesive tape 20.
  • a fissile system is provided which, as in the embodiment according to FIG. 1 a splittable paper 36 and two self-adhesive compositions 37, 38.
  • FIG. 3 a third embodiment of the adhesive tape is shown, which is designated here by 40.
  • the printed adhesive 50 is covered with a removable cover 52, which is segmented by a slot 53 into two sections 54 and 55, but may also be present in one piece ,
  • a paper layer 57 laminated On the back 45 of the carrier 42 is, as in EP 1 076 026 A described by means of a laminating paint 56 a paper layer 57 laminated. This may be the same paper as for the carrier 42. In order to reduce the overall thickness of the system and since the paper ply 57 does not have to take web tension, a thinner paper is preferably used.
  • This paper layer 57 is then provided again with an adhesive 58, which may be analogous to the contact adhesive 50. But here too, lower mass orders are positive for the overall thickness.
  • this side of the adhesive tape 40 is glued manually, i. the technical requirements for the adhesive 58 are not as high as for the adhesive 50.
  • the paper layer 57 on the liner 56 dissolves from the carrier 42, so that no sticky splice residues are formed.

  • the width of the aluminum foil 68 is reduced by the width of the cleavable system 76, 77, 78 plus a predetermined distance from the edge 79.
  • This has a positive effect on the flexibility of the front region in particular.
  • the machinability is improved.
  • This composite is printed in full width on the aluminum side (layer 66) and laminated with a contact adhesive 70 and a removable cover 72 covered.
  • the splittable system in this case consists of a single-ply paper 76 which splits under load in the Z-direction.
